A. 
All finished grading shall match as closely as possible the natural contour of adjacent undisturbed land. Finished slopes in unconsolidated materials should not exceed a ratio of 2:1, horizontal to vertical. Where bedrock is exposed, a slope ratio of 1:1 should not be exceeded. The Soil Conservation District may vary these slope standards, depending on soil or rock type and condition.
B. 
All lots intended for building sites should have a building site where the natural contour, before grading, is less than 25% in grade. Slopes with grades steeper than this percentage may be counted as part of the lot area, but are not to be used as part of the building site. The Zoning Administrator may vary this slope standard with the consent of the Soil Conservation District, depending on slope stability, soil and rock type and condition.
C. 
Sediment and erosion control plans will be designed according to the State Sediment Control Regulations, COMAR 26.27.01 and the criteria set forth in Standards and Specifications for Soil Erosion and Sediment Control published by the Maryland Department of the Environment and available in the Allegany County Soil Conservation District office.

A. 
Minor plans for sediment and erosion control will be prepared according to the standard site plan criteria in § 360-99, Part 4, Zoning, on a worksheet provided by the Planning Commission and signed by the applicant or his agent. This plan will include a plan view of the site and will show the following:
(1) 
A vicinity sketch indicating North arrow, scale and other information necessary to easily locate the site.
(2) 
The location and size of existing and proposed buildings.
(3) 
The volume of grading or earth disturbance involved.
(4) 
Staging of the clearing and grading operation.
(5) 
The depth or height of cut and fill involved.
(6) 
The degree of steepness of any existing slope upon which fill is placed.
(7) 
The degree of steepness of final graded slopes.
(8) 
The proposed manner of handling stormwater runoff.
(9) 
The proposed manner and timing of providing temporary and permanent stabilization such as with vegetation, concrete, blacktop, retaining walls, etc.
(10) 
Proposed erosion and sediment control principles, methods and practices to be employed.
(11) 
A plan view of the site when grading is completed.
(12) 
Approximate locations of streams, ditches or other drainageways are to be included.
B. 
The Soil Conservation District will provide advice to the applicant as necessary during the preparation of this plan.
[Amended 6-10-1992]
Major sediment control plans will be prepared by a registered professional surveyor, landscape architect or engineer licensed to practice in the State of Maryland and will bear his seal. Major plans will be drawn on Mylar or some other translucent material at a size of 24 inches by 24 inches according to the major site plan criteria in § 360-100 of Part 4, Zoning. This plan will include a plan view of the site at an appropriate scale and will show the following:
A. 
A vicinity sketch indicating North arrow, scale and other information necessary to easily locate the property.
B. 
The name, address and telephone number of the owner of the property where the grading is proposed along with the applicant's name and telephone number and the developer's name and telephone number if different from the owner.
C. 
The location and size of buildings.
D. 
The existing and proposed topography.
E. 
The proposed grading and earth disturbance, including:
(1) 
The surface area involved.
(2) 
The volume of spoil material.
(3) 
The volume of borrow material.
(4) 
Limits of grading, including limitations of mass clearing and grading whenever possible.
F. 
Storm drainage provisions, including:
(1) 
Velocities and quantities of flow at outfalls.
(2) 
Site conditions around points of all surface water discharge from the site.
G. 
Erosion and sediment control provisions to minimize on-site erosion and prevent off-site sedimentation, including:
(1) 
Provisions to preserve topsoil and limit disturbance.
(2) 
Details of grading practices.
(3) 
Design details for structural controls.
(4) 
Details of temporary and permanent stabilization measures, including placement of the following statement on the plan.
(a) 
Following initial soil disturbance or redisturbance, permanent or temporary stabilization shall be completed within seven calendar days as to the surface of all perimeter controls, dikes, swales, ditches, perimeter slopes and all slopes greater than three horizontal to one vertical [3:1] and 14 days as to all other disturbed or graded areas on the project site.
(b) 
The requirements of Subsection G(4)(a) do not apply to those areas which are shown on the plan and are currently being used for material storage or for those areas on which actual construction activities are currently being performed or to interior areas of a surface mine site where the stabilization material would contaminate the recoverable resource. Maintenance shall be performed as necessary to ensure that the stabilized areas continuously meet the appropriate requirements of the Standards and Specifications for Soil Erosion and Sediment Control.
H. 
Sequence of construction describing the relationship between the implementation and maintenance of controls, including permanent and temporary stabilization and the various stages or phases of earth disturbance and construction. The sequence of construction shall, as a minimum, include a schedule and time frame for the following activities:
(1) 
Clearing and grubbing for those areas necessary for installation of perimeter controls.
(2) 
Construction of perimeter controls.
(3) 
Remaining clearing and grubbing.
(4) 
Road grading.
(5) 
Grading for the remainder of the site.
(6) 
Utility installation and whether storm drains will be used or blocked after construction.
(7) 
Final grading, landscaping or stabilization.
(8) 
Removal of controls.
I. 
A general description of the predominant soil types on the site, as described by the appropriate soil survey information available through the Soil Conservation District from the United States Soil Conservation Service.
J. 
A statement placed on the plan indicating that the developer shall request that the County approve work completed in accordance with the approved erosion and sediment control plan, the grading or building permit and this Part 2.
(1) 
On all sites with disturbed areas in excess of two acres, approval of the inspection agency shall be requested upon completion of installation of perimeter erosion and sediment controls, but before proceeding with any other earth disturbance or grading. Other building or grading inspection approvals may not be authorized until this initial approval by the inspection agency is made.
(2) 
Approval shall be requested upon final stabilization of all sites with disturbed areas in excess of two acres before removal of controls.
K. 
Certification by the owner or developer that any clearing, grading, construction or development, or all of these, will be done pursuant to this plan and that responsible personnel involved in the construction project will have a certification of training at a Maryland Department of the Environment approved training program for the control of sediment and erosion beginning the project. The certification of training for responsible personnel requirement may be waived by the Soil Conservation District on any residential project involving four or fewer residential units.
L.
